HORSESHOE.

SPECIFICATION formingipart of Letters Patent No. 283,132, dated August 14, 1883, a Application filed March 14, 1819. i

To all whom itmay concern.-

Be it known thatI, JOHN J. MERVESP, of the city, county, and State of New York, have invented. a new and useful Improvement in .Horseshoes, of which the following is a specification- The invention relates tohorseshoes supplied with .detachablecalks.

Heretofore, when a detachable toe-calk was worn too thin, the part of the shoe upon which it rested was also worn. The shoe was also worn when the toe-calk became accidentally detached therefrom. In either case it wasimpossible to attach another calk firmly to the same shoe, as that part of it upon which the secure base for the toefcalk, to which, in the event of the toe of the shoe becoming worn through accident or carelessness, another toecalk can be firmly fastened as well as to facilitate the fastening of the heel-calks. The invention consists in providing the shoe with one or more-longitudinal grooves or recesses and the calk with corresponding ridges or projections to fit in said grooves, (shown in detail in Figures 5 and 6;) or thegrooves in the shoe and projections on the calk may be made transversely, as shown in Figs. 9, 10, and 1,1.

withone or more tapering shanks indented or countersunk at the. end.

Fig. 1 is a perspective view of the shoe with the calks attached. Fig. 2 is a view of the under side of the same. Figs. 3 and 4 are detached views of the heel-calksG D. Figs. 5

' y and 6 are detached views of the grooves and ridges in the 'shoe and toe-calk. Figs. 7 and 8 are modifications of the heel-calks shown in Figs. 3 and 4. Fig. 9 is a detached view. of

the toe-calk L, shownin Fig. 10. Figs. 10]

and 11 are perspective views of a modification of the shoe shown in Figs. l and 2.

After proving from experience that either through accident or carelessness the part of the shoe where the toecalk rested will become Worn, consequently unfit to retain a second calk, in order to prevent this wear and to enable a second calk to be readily and rigidly attached, I make the shoe with one or more ridges to fit those in the shoe.

It also consists in having the heel-calks made longitudinal grooves or recesses, as shown at A, Fig. 5, and the calk with corresponding ridges or projections to fit the grooves in the shoe, as shown at E, Fig. 6. y

The shoe shown in Figs. 10 and 11, in lieu of having the grooves or recesses placed longitudinally, as in Figs. 1 and 2, have them placed transversely the toe-calk shown in Fig. 9, being provided with 1 corresponding grooves and The recesses and ridges in both the shoe and calk may be limited to two or threelarge ones, or agreater number of smaller ones, and may extend either longitudinally or transversely; or the ridges and grooves on the same calk and shoe may be half longitudinal, half transverse. When part of the ridges onthe shoe become worn, in the ceived that, whetherthe grooves and ridges are longitudinal, transverse, or a combination of both, they all effect the same purpose-viz., they keep a level base on the shoe for the reception of another calk, andthey help materially,

in connection with the nails, to keep the calk more securely and rigidly attached to the shoe.

In Fig. 9 the calk is shown with two shanks, r i"; but for general use I prefer to dispense with the shanks. By referring to the drawings it will be,,seen that these calks have two holes in them which are in line with corresponding holes in the shoe, and are attached to the latter by driving nails through these holes into the hoof and clinching them in the usual manner. essary to drive back the nails, when another calk can be fastened-to the shoe. In order to .keep the shoe in position on the horses hoof,

the under side of it is provided with rasp-like To detach them it is only necteeth, or similarly" roughened, as shown in Fig. 2. i

The hcel-calks forthese shoes (shown at O D, Figs. 1 and 2) are made with two tapering shanks, either round or square,'.as shown in Fig. 3, or with one whole shank and half a shank, as shown in Fig. 4. The long shanks are indented or countersunk, and slotted or cut.

to form wings or spurs for the purpose of more easily fastening them to the heels of the shoe.

The calk shown in Fig. 3 may have both shanks indented or countersunk, in order that both may be riveted to the heel of the shoe when a V a suitable press may be used for that purpose.

They are detached from the shoe by cutting off the wings on the end of the shank and punching them out or prying them out with a tapering U-shaped tool. In the eventof the under side of the holes for the heel-calks be coming enlarged, a steel washer may be placed on the end of the shank of the calkbefore it is fastened to the heel of the shoe, in order to prolong the usefulness of the latter.

I claim as my invention- 1. A horseshoe having .one or more longi tudinal or transverse grooves, or a combination of longitudinal and transverse grooves, with a toe-calk having one or more ridges to fit in said groove or grooves, and fastened to the shoe with the same nails which fasten the shoe to the hoof, substantially as shown and described. 7 i

2. A horseshoe having one or more longitudinal grooves, or longitudinal and transverse grooves, and a toe-calk having one or more ridges to fit in said grooves, with the shanks 0- r, substantially as shown and described. p

3. A heel-calk with one or two tapering shanks, substantially as shown and described.

4. Heading down or clinching the end of p the tang or shank of the heel-calk, after passing through the tapering hole in the heel of 5 the shoe, substantially as shown and described.
